| Description: |
Lithium Carbonate (Li2CO3) ; white granular powder; slight soluble in water, melts at 723°C, decomposes above 1310°C; It is prepared commercially by treating the ore with sulphuric acid at 250°C and leaching the product to give a solution of lithium sulphate. The carbonate is then obtained by precipitation with sodium carbonate solution; it is used as a flux in the aluminum, glass and ceramics production to improve the brightness of glazes and increases the firing range. It is a source of Lithia, strong high temperature flux. It is used as an additive in cement industry to improve acceleration and fast setting process. It is used as an additive in floor screeds and tiles. It is used for the production of other lithium chemicals and organic compounds as a catalyst. Pharmaceutical grade of lithium carbonate is used for the primary treatment of depression and bipolar disorder.
